S?ECIFIGATION forming part of Letters Patent No. 633,959, dated September 26, 1899.

Application filed April 15, 1399.

To all whom it may concern:

Be itknown that I, HENRY HAWKES, a citisen of the United States, and a resident of NewYork, (Brooklyn,) in the county of Kings and State of New York,have invented certain new and useful Improvements in Devices for Connecting House Service-Pipes with I'Vater- Mains, of which the following is a specification.

The object of my invention is to produce an improved device by which the house servicepipe can be connected to the water-main.

In the drawings forming part of this specification, Figure 1 is a side elevation of the two parts of the coupling detached. Fig. 2 is an elevation of the two parts of the coupling united. Fig. 3 is an elevation of a vertical seetion,showing the relation of the parts.

The device consists of two parts, one, A, being formed of any suitable metal, such as brass, having at one end a downwardly-projecting part B, which is adapted for connection with the water-main, said part having the guard O and the orifices D. This part extends at nearly a right angle to the other part of the piece A. This part A of the coupling has a valve of any desired form, usually aturning-plug E, and beyond the turning plug it is screw-threaded, as at F. Beyondthe screw-thread extends a conical projection G. c

H is the pipe, of lead or soft metal, which carries the water-supplythrough the house. The end of this pipe is flaring, so as to fit over the conical projection G. The parts are connected by the nut I, which is screwthreaded for a portion of its length, as shown at J, and formed with a conical interior surface, as at L.

In making the connection with my device the water-main is tapped and thepart B connected with main in any suitable manner to form a tight joint. The end of the soft-metal house-pipe is then flared by use of a mandrel, or in any suitable manner, the nut having 45 previously been slipped over said pipe, the

flared end'being placed over the conical projection B. The nut is now screwed onto the threads F, and its interior conical surface bearing against the flared portion of the pipe 50 forces it into contact with the conical projecpieces, sleeves, packing devices, the. joint can be quickly and expeditiously made Serial.

passage through the pipe, thus preventing or 6c retarding the flow of water. It will also be observed that the coupling'is extremely sim ple, consisting of but three parts altogether, thus avoiding the use of extra connecting with a minimum expense as to material, time, and labor.

Another advantage is that excavations made for connecting house-pipes to the mains need not be left open over night, as is the case when the services of a skilled plumber are necessary to make a wiped joint. To make the connection with my device, no more than fifteen minutes are required and no skilled labor necessary, so that the excavation need not remain open, which is of great advantage, as it removes the danger of accidents nowso common in large cities. i

What I claim, and desire to secure by Let- 8o ters Patent, is-

A tap for water-mains consisting of a metal piece having at one end a downward projectionfor connection with the main, a valve in said piece, the other end of said piece having 8 5 of April, A. D. 1899.
